These problems are a part of my Master Thesis Project based on "Security CTF Problems For Beginning Developers Of Low-Resource Real-Time Embedded Systems Software" This reposity contains 5 "coherent" CTF challenges which revolve around a storyline. TODO::Include link to thesis?
- Storyline: Please refer to Section 3 of thesis.
For each problem:
-
Problem Statement: Refer to Section 4.< Problem Number >.2
-
Hints: Please refer to Section 4.< Problem Number >.3
To begin:
cd EmbeddedSecurityCTFs/FreeRTOS/FreeRTOS/Demo/Posix_GCC/make && build/posix_demo <Problem Number>- For example,
make && build/posix_demo 1will launch Problem 1 and so on.
ENJOY!
